I did not get a sense at all that he was making ridiculous demands like you mentioned which yes would be messed up if he did. They’re fighting over simple things like whether to have dancing at mehndi and whether to video record their wedding which seem like were first decided unilaterally by the girl without his input and when he realized she wasn’t going to include those things he’s now saying he wants those things. These are NOT ridiculous demands, maybe he’s trying to create memories for what’s suppose to be a once in a lifetime event. What I did find ridiculous was her not at all soliciting her future husband’s input and suggestions in any of the wedding planning and saying he doesnt have a right to comment on it–she only took his input after he started to get upset. I see his behavior being more reactive to her. Would you book a wedding venue without first running it by your partner? Most would at very least mention it, seems like that wasn’t even done which is why she had to change location after the fact. Communication seems to be a major issue here. Not condoning his behavior because he should remain more level headed but when people are upset especially during moments of stress they often don’t handle it the best way (hence him yelling and putting her down). We have all done it.
